Motor shim plate/w rim for airsoft AEG's

This is a motor shim plate for most AEG's. It has a rim around the edge to help keep it in place. It takes about 1 minute to print. I put one in my cousin's AEG with a v2 gearbox, it's been in there a while and it hasn't given us any trouble yet. I hope this Is within the rules of thingiverse.
